Preheat your oven to 400°F (205°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the gluten-free breadcrumbs, grated parmesan cheese, dried parsley, dried oregano, garlic powder, onion powder, salt, and black pepper. Mix well to evenly distribute the spices and seasonings.
Add the ground beef and egg to the bowl with the breadcrumb mixture. Use your hands or a fork to gently mix everything together until just combined. Avoid over-mixing, as it can result in tough meatballs.
Use a ice cream scoop (#30 portion scoop) to portion out the meat. Shape the meat into balls, about 1.5 to 2 inches in diameter with oiled hands. Place them on the prepared baking sheet.
Shape the meat mixture into balls, about 1 to 1.5 inches in diameter, and place them on the prepared baking sheet. You should get about 18 meatballs total.
Bake the meatballs in the preheated oven for 13-15 minutes, or until they are cooked through and have reached an internal temperature of 165°F (74°C).
Once cooked, remove the meatballs from the oven and let them rest for a few minutes before serving. Alternatively, you can add the meatballs to a pan with your favorite marinara sauce and let them simmer for a few minutes over medium heat to warm the sauce before serving.
Serve the gluten-free beef meatballs with your favorite sauce or pasta. Enjoy!
